O dos laurasiaterios (Laurasiatheria) é un hipotético clado de mamíferos placentarios co rango de cohorte ou superorde, segundo os autores. Está formado por sete ordes con especies actualmente viventes, e seis ordes extintas.

Etimoloxía

O latín científico Laurasiatheria fórmase cos elementos Laurasia-, formado a partir de Lau- (de Laurentia, antigo continente que na actualidade forma parte do cratón de Norteamérica), Asia, e -theria, forma latina plural do grego θηρίον thēríon, "besta salvaxe". Polo tanto o seu significado é "as bestas de Laurasia" (isto é, os animais de Eurasia e Norteamérica).

Ordes

Hoxe en día recoñécense as seguintes ordes con representantes vivos:

Erinaceomorpha
Soricomorpha
Chiroptera
Cetartiodactyla (Cetacea + Artiodactyla)
Perissodactyla
Pholidota
Carnivora

Ademais, estas outras ordes extintas se asignaron á superorde:

Several molecular studies have shown that Chiroptera belong to the Laurasiatheria (represented by carnivores, pangolins, cetartiodactyls, eulipotyphlans, and perissodactyls) and are only distantly related to dermopterans, scandentians, and primates (Nikaido et al. 2000; Lin and Penny 2001; Madsen et al. 2001; Murphy et al. 2001a, 2001b; Van Den Bussche and Hoofer 2004).
